ALBERT BERRYHILL, OF PITTSBURG, PENNSYLVANIA.

d NUT-LOCK.

SPECIFICATION forming part of Letters Patent No. 252,719, dated January2'4, 18 2.

Application filed September 13, 1881. (No model.)

To all whom it may concern:

Be it known that I, ALBERT BERRYHILL,Of Pittsburg, in the county ofAllegheny and State of Pennsylvania, have invented a new and ImprovedNut-Lock, of which the following is a specification.

The invention consists of two grooved blocks held in a longitudinal slotof a plate placed on the bolts and over a recessed plate, which in turnis placed against the fish-plate or against a plate resting against thefish-plate, which blocks are held against thenuts to prevent them fromturning by a locking-wedge placed between them and into the recess ofthe recessed plate, parts of the slotted plate being bent outward toform an aperture to admit the lockingwedge.

Reference is to be had to the accompanying drawings, forming part ofthis specification,in

which similar letters of reference indicate cor- V responding parts inall the figures.

Figure 1 is a plan view of a part of a rail is a longitudinal elevationof the slotted and apertured outside locking-plate. Fig. 4 is alongitudinal elevation of the recessed fillingplate. Fig. 5 is alongitudinal elevation of the first filling-plate to be placed againstthe fishplate.

locking-wedge. Fig. 7 is a perspective view of -one of thelocking-blocks.

The bolts A A are passed through the fishplates B B and through the webof a rail, (1, in the ordinary manner,'a-nd the heads A of the bolts aredriven up firmly against the fishplate B. A metal strip or plate, D,provided at the ends with apertures'E E, of such size as to admit thethreaded ends of thebolts A, and separated a distance equal to thedistance the bolts A are separated, is placed against the-fishplate B,the threaded ends of the bolts A passing through the apertures E. Ametal plate, F, providedwith two apertures, G, of the same size as theapertures E of the plate D, and separated a like distance, is thenplaced against the plate D, the threaded ends of the bolt A passingthrough the apertures G. The plate F is provided with a largerectangular recess, H, in its upper edge.

A plate, J, is provided with two apertures,

Fig. 6 isa longitudinal elevation of the K K,of the same size andseparated a like distance as the apertures E and G. A slot, L, extendsfrom one aperture, K, to near the other, or the two apertures may beunited by the slotL. Notches or cuts M extend upward and downward fromthe slot L into the plate J, at or near the middle of the slot, thuspermitting the part N of the plate between the cuts M to be bentoutward.

Blocks 0 are provided in the top and hotton with grooves P, of the samewidth as the thickness of the plate J, each groove forming two flanges.or ridges, Q Q, at the edges of these blocks 0, of which ridges theinner one, Q, must not be of greater thickness than the distance betweenthe plates D and J-that is, the ridge orflange Q must not be thickerthan the plate F. The block 0 is to be ofsuch size that it can be 3passed into or, through the aperture K, connected with the slot L. Alocking-wedge, B, consists of a-segmentally-bent wire having twoupwardly projecting and converging arms, S S, and is of such size astofill the space between the blocks 0. In place of the spring-wedge R, anyother suitable fillingpiece may be inserted between the blocks 0.

The operation 'is as follows: The plates D and F having been placed onthe bolts A, as previousl y mentioned,the blocks 0 are passed into theaperture K of the plate J, and are passed into the slots L, the ridges Qof the block being on the front side and the ridges Q on the rear of theplate J. The plate J is then placed against the plate F, the ends of thebolts A passing through the apertures K. Then the nuts T are screwedonthebolts A, and are turned down tightly. Then the blocks 0 are pushed tothe ends of the plates J to rest against the nuts T. For the purpose oflocking the blocks 0 in this position the part N between the notches Mis bent outward and the locking-wedge R is inserted between the blocks0, whereby these blocks will. be held in their position, resting againstthcnuts T, and thus prevent the nuts from turning. After inserting thelocking-wedge R the parts N 'are bent back again. If the nuts are to beloosened or removed, all that is necessary is to bend the parts Noutward, remove the wedge R, and push the blocks 0 to the middle of theslot L.

Having thus fully described my invention, I

claim as new and desire to secure by Letters slotted plate J, the plateD, the blocks 0, and :0 Patent the wedge or filling piece R,substantially as 1. In a. nut-lock, the combniation, with the hereinshown and described, and for the purholts A and nuts '1, 0f the recessedplate F, the pose set forth.
